Tallysman Introduces LNAs for Choke Ring Antennas

Tallysman has announced the availability of the TW600 family of high performing economical wide band LNAs for choke ring antennas. The TW600 family of low noise amplifiers (LNA) are optimized for all GNSS bands utilized by the GPS, GLONASS, Galileo, and BeiDou satellite systems. This LNA is designed for integration into existing choke ring antennas thereby upgrading them to receive the entire GNSS band or a subset thereof.

There are four different models - TW60x, TW 61x, TW62x and TW63x - with options of 35 dB and 50 dB gain. Thus these LNAs are ideal for upgrading existing choke ring antennas with Dorne Margolin/ EDO elements to receive the new and expanding GNSS signals.

The LNAs provide consistent gain across the full bandwidth and include filters for suppression of out-of-band interfering signals such as cellular LTE and Iridium signals, while maintaining a low noise figure, high third order intercept point, small group delay, and low power consumption. The enclosure is designed to fit a wide variety of choke ring antennas currently deployed.

TW61x:  All GNSS Signals (1164 - 1300 MHz + 1559 - 1610 MHz)
TW62x:  L1/L2, G1/G2, B1/B2, E1 + L - band (1195 - 1254 MHz + 1525 - 1610 MHz)
TW63x:  L1/L2/L5, G1/G2/G3, B1/B2, E1/E5a+b (1164 - 1254 MHz + 1559 - 1610 MHz)
TW60x:  All GNSS Signals + L - Band (1164 - 1300 MHz + 1525 - 1610 MHz)

The LNAs are REACH and ROHS compliant. Click here to know more.
